I've tried to watch every episode of Fringe, but this is the one that has really caught my attention. The story about the boy being found underground was interesting.
I liked the connection the boy had with Olivia. They seemed to work well together and I'm glad she was able to keep her promise to the child. The boy was very creepy, I even thought he was about to jump and bite whoever came too close to him.
I still don't like Olivia that much. She lacks something, passion, charisma. However, Walter steals every scene. His comments are sometimes hilarious and he seems to live in his own world. It's also nice to see a show where you get to see the main characters' personal lives, in this case, Olivia's family.
The end scene was creepy too. Who was that bald guy?
